Sophon said the weapons – six shotguns that riot-control police used to fire rubber bullets with, 12 teargas launchers, three .38 pistols as well as six police personnel pistols – had gone missing from police trucks during the December 26 clash between anti-government protesters and police force at the Thai-Japanese Stadium. So far, only one 9mm pistol belonging to a Nakhon Sawan police officer has been retrieved and the suspect arrested, he added.
